SURFACE MODIFIED FLUOROELASTOMER SEALING MATERIAL

摘要

The object of the present invention is to provide a surface modified rubber and a seal material which enable obtaining a rubber molding being excellent in nonadherence, low friction, abrasion resistance and plasma resistance while retaining strength, compression set, sealing capability and deformation follow-up properties inherently possessed by a rubber material. The process for producing a surface modified rubber according to the present invention comprises contacting a treatment liquid containing a monomer having a polymerizable double bond, a polymerization initiator and a solvent with a rubber base material; and heating the thus contact treated rubber base material so that the monomer is polymerized to thereby modify the rubber base material at its surface and vicinity thereof.
